' Application filed November- 18, 1921. Serial No. 516,171.

Be it known that I, CLEARENCE B. ONEILL, a citizen. of the UnitedStates, residing at Clymer, in the county of Indiana and tate ofPennsylvania, have invented a new and useful Nonset Automatic Stop,which the following is a specification.

This invention relates to graphophone' attachments, the primary objectof the invention being to provide means for automatically controllingthe brake lever of a graphophone to cause the motor to shut off when thereproducer forming a part ofthe graphophone has reached the innermostgroove of a record.

I Another object of'the invention 1s to provide a device of thischaracterwhich may that changes in the precise embodiment of theinvention'herein disclosed, may be made within the scope of what isclaimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 is a side elevational view disclosinga portion of a phonograph turn-table and illustrating the invention asapplied.

Figure 2 is a fragmental plan view of a turn-table, the same away todisclose the brake lever.

Figure 3 is a sectional view taken on'l-ine 3-3 of Figure 1. I

Figure 4 is a rear elevational view of a reproducer and tone arm, theturn-table being shown as broken away.

Figure 5 is a side'elevational view of the same.

Figure 6 is a fragmental detail view of a record which is formed with arecess portion to cooperate with the stopping device.

Figure 7 is a sectional view taken on line 7-7 of Figure 5.

Figure 8 is a modified form of lever securin -means. I

Re errin to the drawings in detail, the reference character 5 designatesthe turnbeing partly" broken table of the usual graphophone, which sup:ports the usual record or music tablet. The

reference character 6 designates the usual tone arm which carries thereproducer 7,-

at one end thereof. 1

The brake arm which cooperates with the turn-table 5 in designated bythe reference character 8, the brake arm being of the usual constructionand formed with a lateral extension 9 carrying the brake foot 10'designed to engage the turn-table to prevent rotation thereof." Thisbrakearm is normally held under'the tension of the coiled spring 11 thathas one endthereof connected to the'arm-S, the'opposite end'thereofconnected to the lever 12 which is pivotally I mounted adjacent tothefarm. '8. Q

A lug indicated at 13'eXtends upwardly from the arm 8 and is-engaged bythe notched portionof the arm'l2 to'hold the'spring 11 under tension,and'retain the foot 10 out of engagement with the turn-table whenv theturn-table is in operation. Pivotally supported adjacent tothezt'o'nearm 6 isan arm=14 which is relatively wide and curved to conform to thecurvature of the tone arm 6.

A. bracket 15 has pivotal connection with the arm, the bracket beingsecured to the I 1 top of the graphophone cabinet, as clearly shown byFigure 1 of the drawings.

Connecting the arms 12 and 14 is an actuating rod 16 which has anupwardly extending end' portion 17 connected to the lug 18',

formed integral with the arm 14. Thus it will be seen that movement ofthe arm 1.4 produces a relative movement of the rod 16, and'arm 12, torelease the brake arm 8 to permit the coiled spring 11 to operatethebrake arm to shut off the operation of the machine. v

Bearing members 19 form a part of the tone arm and are shown as disposedon the under side thereof, the bearing members being designed to receivethe reciprocating .1 1

w offset and contacting with the arm 14, the opposite end thereofcontacting with the operating rod 20 which has one end thereof pivotedoperating lever 21 which is pivotally mounted at one end of the arm 22.pivoted foot 23'is carried at the lower end of the lever 21, and isformed with a felt covering adapted to cont-act with the surface of therecord or music tablet. This pivoted foot 23 is normally urgedrearwardly'as by means of the spring 24 which is shown as havingconnection with the lever 21 at one end, and bearing against the pivotedfoot 23 at its other end.

A recess 25 is formed in the record or music tablet at a point adjacentto the central opening thereof, where the same lies within the path oftravel of the pivoted foot 23 when the reproducer has moved to the limitof its innermost movement, whereupon the pivoted foot 23 contacts withthe walls of the recessed portion.

It follows that when the pivoted toot contacts with the walls of therecessed portion, the pivoted lever 21 is moved to a position as shownby Figure 5 of the draw ings, with the result that the operating rod 20is moved longitudinally of the tone-arm 6 causing a relative movement ofthe arm 14, and rod 16, releasing the arm 12 and permitting the springto move the brake arm to prevent movement of the turntable.

The bearing 1 iember as shown by Figure 8 of the drawings, includesopposed sections 26 which may be clamped around the tone arm of aphonograph as shown by Figure 8 of the drawings, and held in suchposition by means of the bolt 27.

Having thus described the invention what is claimed as new is:

1. In comibnation with the tone-arm, turn-table and music tabletsupported on the turn-table, a lever supported adjacent to one end ofthe tone arm and carrying a pivoted foot contacting with the musictablet, said music tablet having a recessed portion lying within thepath of travel or" the pivoted foot, a brake arm, means for connectingthe lever and brake arm, and said pivoted.

foot adapted to contact with the walls of the recessed portion to causethe operation of the lever and connecting means between the lever andbrake arm.

2. In combination with the tone arm, turn-table, and music tabletsupported on the turn-table, an operating rod carried by thetone arm, abrake arm for controlling movement of the turn-table, means for connecting the operating rod and brake arm to cause the brake arm to stoprotation of the turn-table, a lever supported adjacent to one end 01 thetone arm and contacting with the operating rod, and means at one end ofthe lever and normally engaging the music tablet for moving the lever tooperate the operating rod.

3. In a device of the character described, an operating rod, anactuating rod, a brake arm, a pivoted arm having connection with theactuating rod and contacting with the brake arm, to normally hold thesame out of operation, a pivoted arm having connec tion with theactuating rod and contacting with the operating rod, a lever carrying afoot, and contacting with the operating rod, and said foot adapted to bemoved to cause a relative movement of the operating rod, actuating rodand arm, to release the brake arm.

In testimony that I claim the foregoing as my own, I have hereto ailixedmy signature in the presence of two witnesses.
